Filed: 1970-02-12
Abstract: 1293465 Automatic vending systems ZELLWEGER Ltd 12 Feb 1970 [26 March 1969] 6801/70 Heading A4T [Also in Division G4] In an automatic vending system an article is provided with information, e.g. a price or weight label, which is automatically read and, if the article is found to be within predetermined limits it is automatically released to the customer. In this figure an article 1 is marked and is passed on a conveyor into the reading zone 2 of a reader 3. The reading from the article is passed by way of a line 3b to a computor 4 which identifies the article from its marking and passes the result to a store 5. The article then passes by means of a conveyor 6 to a measuring device 7 which weighs the article and passes this information to a comparator 8 which also receives the signal stored in the store 5 by way of a line 5a. If the two signals are in general agreement the article is passed by a conveyor 9 to a container 11 and a signal is passed to a totaliser 13 which passes the signal to a cash register 15. This system is repeated for as many items as the customer passes through the system. If the comparator 8 finds the two signals incompatible the article is returned by a conveyor 10 to the start of the system. After payment indicated by the register 15 has been made, or debited to an account, the customer presses a button 12 on the reader 3 and the compartment 11 releases all the articles therein. In the event of a fault or unsuccessful reading a convey 6a may return the article to the start of the system. The sequence of reading and weighing may be reversed or both may be performed simultaneously.

Title: A weighing scale
IPC: G01G11/02
Filed: 1925-03-12
Abstract: 234,778. Toledo Scale Co., (Assignees of Hem, H. 0.). May 31, 1924, [Convention date]. Automatic-feed weighers; indicating and registering mechanism. - Relates to weighing-apparatus for indicating the total weight of material which flows over the platform in any period of time, of the type comprising a disc rotated at a speed proportional to the speed of the material over the platform, and a roller which engages the disc and is adapted to be moved radially over the face of the disc, proportionately to the movement of the platform and consists in that the radial movement of the roller is caused by tilting it about an axis perpendicular to the face of the disc under the influence of means connected to the platform. As shown, the commodity to be weighed is carried by a conveyer belt 2, Fig. 1, over a series of rollers 1 mounted on a platform 3. The platform levers 6, 7 are connected by a draw-rod 11 to a pendulous weighing-scale 12. An integrating-mechanism is situated in a housing 30 on ton of the weighing-scale 12, and comprises a disc 33, Figs. 5 and 7, rotated, through a flexible shaft 35 connected to one of the rollers 1, at a speed proportional to the speed of the belt 2. The motion of the disc 33 is communicated through a pair of rollers 56, 57 to a drum 60, connected through reduction gearing to a counter 70. The rollers 56, 57 are mounted in a cage 52, journaled in a frame 48, which is in turn mounted on rollers 50, 51 and capable of movement parallel to the axis of the drum 60. The cage 52 is provided with a downwardly extending rod 80 pivoted to a horizontal rod 79, which is moved in accordance with the load on the platform 3. The effect of a change in the load is to tilt the rod 80 and cage 52, thus setting up a horizontal force between the disc 33 and the roller 56 which causes. the frame 48 to move until the rod 80 is again vertical; in which position the distance between the point of contact of the roller 56 and the disc 33, and the axis of the disc 33, is proportional to the load. A stop 85 prevents the rollers 56 passing the axis of the disc 33, and a second stop 86 co-operating with a projection 87 on the cage 52 prevents the roller's staying at the axis upon the application of a load.

Abstract: 577,473. Manures. TOWNSEND, C., SMALL, F. H., and CORNISH MANURES, Ltd., (formerly CORNISH FISH PRODUCTS (LONDON), Ltd. April 17, 1944, No. 7061. [Class 111] In the production of colloidal peat, for use in agriculture, peat, preferably reduced to a fine state of subdivision, is subjected to the action of an acid, e.g., sulphuric acid, for a period of e.g., 24 hours. A precipitant or coagulant is mixed into the mass and the supernatant liquid drawn off after the settlement of the precipitate. The pH value of the mass is then adjusted to 6 by the addition of an alkali or calcium carbonate, and the mass dried and inoculated with an organism for stimulating plant growth. In a modification, the peat is passed through high pressure rollers and the expressed liquor subjected to acid treatment and allowed to rest for a period before the addition of the precipitant or coagulant, preferably aluminium sulphate. After the precipitate has settled, the supernatant liquid is drawn off, and sufficient alkali or calcium carbonate added to the precipitate to impart a pH. 6 thereto. The peat solids from the pressure rollers, in discrete form, are added to the conditioned precipitate, and the mixture, after being dried, is inoculated with the organism, e.g., phycomyces.

Abstract: 1502634 Testing ignition circuits REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 19 Feb 1975 [20 Feb 1974] 7069/75 Heading G1U Correct combustion of the gaseous mixture in a controlled ignition heat engine is monitored by examining the waveform of current pulses fed to the spark-plugs by a current generator separate from the ignition circuit. A high voltage source (e.g. greater than 500v) is connected to the plug central electrode via a high resistance, and has a current measuring shunt in series Fig. 1 (not shown). A correct current waveform 31, Fig. 4 has a spike 32 representing the spark, and a plateau 33 representing current flow through the ionized burnt fuel mixture. In the detection circuit Fig. 2 connected at 12 across the current shunt, a first comparator 14 has a high reference level to separate rut spark pulses 32. A gate 17 is blocked while these occur, and consequently comparator 18 set to a lower reference level only responds to the plateau portions 33. Spark pulses increment a counter 21, and plateau portions reset the counter to zero, thus for correct operation, the counter 21 does not provide an output. If combustion fails for more than n consecutive ignition pulses, decoder 23 provides an output 24 which may be used to control the fuel supply, engine operation, or an alarm. In a further detector Fig. 3 (not shown), the failure of spark pulses to appear at output 16 also causes a warning signal output.
